Efeitos da parede de levedura em dieta úmida na microbiota fecal, na produção de gás e na morfologia intestinal de gatos adultos

The aim of this study is to evaluate the effects of yeast extract (EPL) in the moist diet on the fecal microbiotal, gas production and intestinal morphology of adult cats. Twenty adult cats from both sexes were randomly assigned to four treatments: 1) moist commercial diet (control); 2) control + 0,2% yeast extract dry matter; 3) control + 0,4%; and 4) control + 0,6%. Fecal microbiology and intestinal morphology were performed by radiographic, ultrasound, colonoscopy and intestinal biopsy exams for histology. There were no significant differences (P>0,05) for lactic acid bacteria counts and clostridium-reductor, gas area in the bowel (radiographic), wall thickness of the colon (ultrasound) and colonocytes count/globet cells (histology). Through colonoscopy, changes in characteristics of the intestinal mucosa in animals receiving treatment 4 were noticed. It is concluded that the addition of up to 0.6% EPL had no effect on the parameters evaluated, but further studies are needed to understand the action mechanisms and additive effects for domestic cats.

Punção aspirativa de linfonodo axilar guiada pela ultrassonografia é eficaz como método de predição de acometimento linfonodal em pacientes com câncer de mama?

OBJETIVO: Avaliar a viabilidade e acurácia diagnóstica da ultrassonografia pré-operatória combinada com biopsia por agulha fina (US-PAAF) e do exame clínico da axila em pacientes com câncer de mama.MÉTODOS: Neste estudo prospectivo 171 axilas de pacientes com câncer de mama foram avaliadas pelo exame clínico e ultrassonografia (US) com e sem biopsia por agulha fina (PAAF). Os linfonodos com espessura cortical maior que 2,3 mm na ultrassonografia foram considerados suspeitos e submetidos a US-PAAF.RESULTADOS: A análise de regressão logística não mostrou correlação estatisticamente significativa entre exame clínico e axilas positivas no exame patológico. Em relação à avaliação axilar com US, o risco de achados anatomopatológicos positivos aumentou 12,6 vezes, valor Kappa de Cohen foi de 0,12 para exame clínico, 0,48 para US e 0,80 para US-PAAF. A acurácia foi de 61,4% para o exame clínico, 73,1% para os US e 90,1% para US-PAAF. Análise Receiver Operating Chracteristics (ROC) mostrou que uma espessura de 2,75 mm cortical correspondeu à mais elevada sensibilidade e especificidade na predição metástase axilar (82,7 e 82,2%, respectivamente).CONCLUSÕES: A US combinada com aspiração por agulha fina é mais precisa que o exame clínico na avaliação do status axilar no pré-operatório em mulheres com câncer de mama. Aquelas que são US-PAAF positivo podem ser direcionadas para esvaziamento linfonodal axilar imediatamente, e somente aqueles que são US-PAAF negativos devem ser considerados para biópsia de linfonodo sentinela.

Colangiohepatite Felina

Cholangiohepatitis is a common hepatic disorder in cats that is second only to hepatic lipidosis in frequency. The cholangitis-cholangiohepatitis complex is known as the diseases that involve the biliar tract inflammation and may extend to the liver. The classification of the cholangiohepatitis is still controversial, in this present study the following classification was used: Acute Cholangiohepatitis, Chronic Cholangiohepatitis, Lymphocitic Cholangitis. The cholangiohepatitis may be associated with pancreatitis and inflammatory bowel disease, this association is known as feline triaditis. The diagnosis is based on the clinical signs, alterations in laboratory exams and ultrasonography alterations, but the definitive diagnosis is only possible through liver biopsy. The treatment for each type of cholangiohepatitis differs, hence the importance of the right diagnosis. This study aimed to do a review over the ethiology, clinical presentation, diagnosis and treatment for this disease

Neoplasia mamária em cadelas: aspectos clínico-cirúrgicos

Oncology is presenting an important role in clinical practice as a speciality in recent years in Veterinary Medicine. Mammary gland tumors are detected mainly in old and middleaged bitches that are sexually intact or spayed and the caudal abdominal and inguinal mammary glands are the most affected and they present a percentage up to 75% of malignancy. The majority of dogs with mammary neoplasms are clinically healthy at the time of diagnosis and the tumors can be identified by the owner or a professional during a routine physical examination. Cytological examination of fine needle aspirates can be performed. This procedure is easy and low cost and some criteria that may indicate malignancy are evaluated, however to obtain a definitive diagnosis is performed histopathology of the excised tissue or from biopsy. Regional lymph nodes are the first lymph node to receive lymphatic drainage from the neoplasm. They are at the highest risk of regional metastasis, while the lung is the most common site for distant metastasis. Determining the clinical stage enables the definition of the extension of the tumor. As a consequence, this allows a prognosis to be established and treatment to be planned. The type of therapy to be chosen incites controversy since there are numerous treatment options described, but the surgery is the chosen treatment. However, surgery is not always effective for malignant tumors, and recurrences may occur and in these cases, auxiliary chemotherapy treatments are used. The prognosis for animals that have mammary tumors depends on several factors, such as: size, stage, type of tumor cells and clinical behavior of the tumor, age and medical condition of the animal, and presence of metastasis. Because of this, more detailed studies are needed based on epidemiological surveys in order to provide more informations about risk factors, prevalence and follow-up after treatment of mammary...

Osteossarcoma apendicular: revisão de literatura

Osteosarcoma is the most common primary bone cancer in dogs. It affects most commonly dogs of big or giant breeds with 7 to 8 years and the etiology is unknown. Osteosarcoma is defined as a bone matrix-producing malignant mesenchymal tumor and has a predilection for the metaphyseal region of appendicular skeleton, however, it can affect axial skeleton and soft tissues. Distal radius is the most commonly affected site. The definitive diagnosis of osteosarcoma can be obtained with history, physical examination, radiographs and biopsy. Lung is the most common organ for metastatic disease. The mainly treatment for osteosarcoma is limb amputation and systemic chemotherapy for metastatic disease control. Limb-sparing surgery is a viable alternative to amputation for dogs with concomitant conditions that impede limb amputation. Palliative treatments for osteosarcoma have been studied such as local and systemic radiotherapy, immunotherapy and biphosphonates. This study has the objective of presenting the aspects of diagnosis and treatment for appendicular osteosarcoma

Platinosomíase em felinos domésticos: um diferencial para obstrução biliar

The platinosomiase is a disease the hepatobiliary system of domestic felines being caused by trematode Platynosomum fastosum. The life cycle of the parasite includes the presence of three intermediate hosts (snails, terrestrial isopodes, lizards or frogs). The cat is considered definitive host of the parasite and acquires the infection eating a vertebrate intermediate host containing metacercariae. The adult parasites generally inhabit the liver, gallbladder and bile ducts of cats. The severity of clinical manifestations depends mainly on the number of flukes in the biliary tract. Many animals are asymptomatic or exhibit nonspecific clinical manifestations such as anorexia, lethargy, weight loss, vomiting and diarrhea. In large infestations can occur biliary obstruction resulting in jaundice, cirrhosis, hepatitis cholangiohepatitis and even death. The definitive diagnosis is accomplished through by the detection of fluke eggs in feces or through laparotomy and liver biopsy. Treatment should be based on the use of anthelmintic for the elimination of the parasite and supportive therapy for the animal. Prevention is difficult due to predatory nature of the cat. The control can be accomplished through periodic fecal examinations
